Belém is on the banks of the Bay of Guajará, which is formed by a set of islands and river mouths on the estuary of the Amazon river. Its river port helps putting into motion the Northern region of Brazil.
The city was established in 1616, after the construction of "Forte do Presépio", today "Forte do Castelo", on the banks the Pará river. Belém is, in a way, a synthesis of the culture and the history of Pará and the Amazon with native indian influence in the food and culture. It became an extremely wealthy city with the Rubber Boom at the end of the 19th century and many beautiful colonial buildings from this era are still visible.
Every year, in the second Sunday of October, it is celebrated in Belém, one of the largest catholic procession of the world, Círio de Nazaré.
Huge bus terminal a few kilometers east of the center. Many local buses pass here.
It is possible to travel by air-conditioned coach to Belém from most major points in Brazil. However, due to its relative isolation, travel times can be quite lengthy (Examples 12h to São Luís, 27 hours to Fortaleza) 36 to 42h to salvador- especially from the south.
There are regular international flights linking Belém to Cayenne, Georgetown, Paramaribo and Miami, and many direct domestic flights linking Belém to Brasilia, Fortaleza, Manaus, Rio de Janeiro, Sao Paulo and Macapá.
Bus Pratinhas to/from Presidente Vargas, and Marex to/from Praça da República.
Taxi to center R$ 20-30 (you can try to negotiate, but you can also help the taxi association to promote the «taximetro», with fair prices for everyone).
Passenger terminal at the north end of the docks. Many daily boats to nearby islands, including twice to Rio Branco.
Also to Macapá, Santarém Belem and Manaus, with connections further north and west. Locals sling hammocks to sleep but air conditioned cabins are available on the larger boats. This is a great way to travel see (and hear) the river, and meet people.
There is one major long distance coach terminal at Sao Braz. There are many local busses travelling all over the city at often exhilirating and reckless speeds. The number of buses passing Avenida Presidente Vargas is nothing short of astonishing, and you can get virtualy anywhere within Greater Belém from here. The challenge lies in finding the right bus, and also getting onboard, as it will stop anywhere on a stretch of some 2-300 metres, or atempt to pass straight. Do as the locals: Wave and run for it!
Another transport "hub" is in front of the bus terminal, next to São Bráz, only slightly less chaotic.
Most buses run until about 11PM, but minibuses go virtually around the clock on major roads.
Belém is a lively and friendly city but it can look quite unappealing at first sight. There are a lot of modern high rises, but between them particularly in Cidade Velha and Campinas there are a vast number of well preserved colonial buildings, from the rubber boom and earlier. Many of the grander ones now house official bodies and there has been a recent drive to preserve them.

Belém is now a large city, take care when walking after nightfall along Presidente Vargas and the back streets that lead off from it. Although no worse (and perhaps better) than other Brazilian cities there is still a lot of poverty so try not to have jewellery or cameras on show when walking around. The city is generally safe and friendly during daytime. Estacao das Docas is always a safe if rather touristy option. The Umarizal area has up market local bars and restaurants. Avenida Joao Paulo Segundo (previously called Avenida Premeiro de Dezembro) has some more "down to earth" and very local bars. Generally there is a lot of night life Thursday, Friday and Saturday ask for advice. Although worth a visit try and avoid Estacao da Docas which is really only for tourists.
While in Belém you should not drink tap water, though you can use water from the tap to wash vegetables, brush your teeth, etc. As Belém is located approximately 100 mi south of the equator, the sun is particularly strong year-round, so fair-skinned travelers should apply sunscreen on a daily basis. Additionally, be sure to apply mosquito repellent when going out after sunset. Malaria is not a major concern in Belém, but if you are traveling to remote areas of Pará during the rainy season you should, after consulting with your doctor, consider taking malaria pills. The CDC recommends getting a Yellow Fever vaccine for travel in Pará and many other parts of Brazil. You can learn more about recommended vaccinations for Brazil on the CDC website .
Ilha do Mosqueiro is the closest beach area (after Outeiro) to Belém, some 80 km away. The island is surrounded by sandy river beaches (some developed more than others) with fresh water and because of the size of the estuary often large waves. Buses at least every half hour from the bus station. Boats on weekends and high season.
Icoaraci some 25 km north of the centre offers a pleasant bayside walk with quite a few bars and restaurants. Car ferry for Ilha do Marajó leaves from here. Local buses from downtown.
Salinópolis or Salinas offers the nearest sea beaches. It is a beautiful place with nice beaches (Atalaia, Maçarico, Farol Velho etc...), a three hours from Belém, and it is a good place to visit/stay (at least one night). The original town is Salinopolis. Atalaia and Farol Velho are beautiful beaches except at weekends and holidays when they can resemble car parks with thousands of visiting cars from Belem. If you drive along the beach far enough you will get away from the crowds, but if you have a car be careful of soft sand and the tide!
Ilha do Marajó is possible as a day trip, but consider spending at least one night. Many agencies offer packages, but you can usually do the trip for cheaper on your own. .
